4.129 × 10−4

Answer 1

To determine which number is higher than \( 1.429 \times 10^{-4} \), we can compare each of the given options.

1. \( 1.429 \times 10^{-5} \)

   • \( 1.429 \times 10^{-5} = 0.00001429 \)
   • This is lower than \( 1.429 \times 10^{-4} = 0.0001429 \).

2. \( 1.429 \times 10^{-3} \)

   • \( 1.429 \times 10^{-3} = 0.001429 \)
   • This is higher than \( 1.429 \times 10^{-4} \).

3. \( 1.429 \times 10^{-6} \)

   • \( 1.429 \times 10^{-6} = 0.000001429 \)
   • This is lower than \( 1.429 \times 10^{-4} \).

4. \( 4.129 \times 10^{-4} \)

   • \( 4.129 \times 10^{-4} = 0.0004129 \)
   • This is also higher than \( 1.429 \times 10^{-4} \).

So, the numbers that are higher than \( 1.429 \times 10^{-4} \) are:

• \( 1.429 \times 10^{-3} \)
• \( 4.129 \times 10^{-4} \)

Both of these options are correct responses.
